What is concussion?

A

A traumatic brain injury that changes the way your brain functions

21
Q

What is profound delirium?

A

Caused by i.e., drugs, alcohol, dehydration, fever, hypercalcemia, brain tumour

22

A

Gives a SCF sample – viral and bacterial meningitis
Higher than L2/L3

24
Q

What is hydrocephalus?

A

Blockage in 3rd-4th ventricles e.g., tumour resulting in build up of CSF

25
Q

What is chronic hydrocephalus?

A

Q

What is proptosis?

A

Bulging of the eye – e.g., rhabdomyosarcoma (paediatrics – muscle that controls the eye)

38
Q

What is ptosis?

A

Eyelid droops – compression of the sympathetic nerve

39
Q

What is Left Field Homonymous Hemianopia?

A

Homonymous hemianopia (also called hemianopsia) means that the patient cannot see anything in the entire left or right visual field in both eyes - Damage to the optic chiasm

40
Q

What is Bitemporal hemianopsia?

A

A type of partial blindness that is associated with lesions of the optic chiasm, the area where the optic nerves from the right and left eyes cross near the pituitary gland.

41
